Abstract
A gas turbine engine includes an open rotor configured to rotate with a nose cone. A heat exchanger is positioned within the nose cone and a system for using a working fluid. An inlet from the system is connected to the heat exchanger and an outlet from the heat exchanger connected back to the system. A central opening is in a central portion of the nose cone to deliver cooling air across the heat exchanger, and a duct downstream of the heat exchanger to direct the cooling air radially to at least one static opening such that the cooling air can move radially outwardly through static structure and be directed into a propulsion airflow path. A method and a heat exchange system are also disclosed.

A gas turbine engine comprising:
- an open rotor configured to rotate with a nose cone, the open rotor having propeller blades with no housing radially outward of the propeller blades;
- a heat exchanger positioned within the nose cone and a system for using a working fluid, an inlet from the system connected to the heat exchanger and an outlet from the heat exchanger connected back to the system;
- and a central opening in a central portion of the nose cone to deliver cooling air across the heat exchanger, and a duct downstream of the heat exchanger to direct the cooling air radially to at least one static opening such that the cooling air moves radially outwardly through a static structure and be directed into a propulsion airflow path, wherein the at least one static opening is in a swirl recovery vane of the open rotor on an outer housing.
